Abstract

1413260 Positive clutches HURTH VERWALTUNGS GmbH 27 Feb 1974 [28 March 1973] 8963/74 Heading F2C A friction synchronizing ring assembly for a positive double clutch in a motor vehicle changespeed gear comprises synchronizing cones 22, 23 interconnected by baulk pins 20, the assembly having a ratio D/A in the range 3À4 to 4À0 where D is the maximum diameter of the cones and A is the overall length of the assembly. The ratio D/A may be 3À6. As shown the baulk pins 20 pass through holes 19 in a flange 18 of a clutch sleeve 17 to prevent engagement of the latter with clutch teeth 28, 29 on gears 11, 12 until synchronism is attained. During initial clutch engaging movement of the clutch sleeve 17 the synchronizing rings 22, 23 are moved into engagement with friction rings 24, 25 fast with the gears 11, 12.
